Explanation

Formula: PPI = 5556.977595779922 x 2.54 / diagonal_cm. Why: this route fixes the resolution profile to WU4K 5120x2160, so diagonal pixels stay constant for every calculation.

WU4K 5120x2160: a fixed resolution profile with 5120 × 2160 pixels, used as the density basis for this page.

Diagonal size (centimeters): a screen-density quantity in this family that depends on the selected resolution profile.

Pixels per inch (PPI): a screen-density quantity in this family that depends on the selected resolution profile.

This route is useful when estimating screen sharpness, reading distance suitability, and display density for WU4K 5120x2160.

This page is profile-dependent rather than universal because PPI, screen size, and pixel pitch depend on the selected resolution profile (WU4K 5120x2160).

Method & Display Profile

Method basis: fixed WU4K 5120x2160 pixel grid (5120 × 2160) with one constant diagonal-pixel count for this route.
Profile reference: WU4K 5120x2160 (5120 × 2160), so size, PPI, and pixel-pitch values all stay tied to the same display grid.
Consistency rule: calculator output and common-value rows keep the same fixed display profile in both directions.
